IMPROVEMENT IN RING-SPINNING FRAME.

TO ALL WHOM IT MAY CONCERN:

Be it known that I,-JOHN ASHWORTH, of North Andover, inthe county ofEssex, and State of Massachusetts, have invented an Improvement in theMode ofConstructing and Arranging Spinning-Rings in Ring-Spinners, socalled; and I do hereby declare that the following is a lfull, clear,and exact description of the same, taken in connectionwith theaccompanying drawings, making a part of this specification, in whichlFigure 1 is a plan of the'ring and a portion of the copping-rail, with apart in horizontal section, to show the screws which confine the ringthereto. Y A 4 Figure Zis a front elevation of the same, and

Figure 3 is a vertical section through the centre ofthe ring, andtransverse to the rail.

The subject-matter of my invention relates to the method oi'attachingand adjusting the-rings of ringspinners, so called, so that thering may be readily and accurately set concentric with the spindle.` Inthe construction ol' ring-spinning frames, when a long row of spindlesis used, it isA-a matter ofgreat nicety and diiieulty to make all of thesockets for the rings in the eopping-rail accurately concentric withtheir respective spindles, and if so made at rst, they are liable to getout of adjustment by wear ofthe spindles or the springing of the rail,and therefore require some means of correcting the evil.

My invention consists in securing the ring to the rail by means of aclamping-screw and two set-screws, by the joint action of which the ringmay be moved a short distance in any direction parallel to the plane ofrevolution of the spindle, by which means each ring may be brought to aposition concentric with the spindle independently ofthe other. I

In the drawings, vA is the spinning-ring, made in the usual way, 'allelower part of which is set in a circular socket in the copping-rail B,which is made somewhat larger than the exterior diameter of that 'partof the ring` which it encloses, and rests' upon the top ofthe rail bymeans of the shoulder C. Through the front sideof the rail, and oppositeto the centre of the ring, is inserted a clamping-screw, D, the point ofwhich screws into the ring, and the head of which rests upon the rail ina ceuntersink.

Upon either side ofthe screw D are insertedl twoset-serews, E E,\whichscrew into the rail, and the points of which bear against' the outsideof the ring, as shown in fig. 1.

By means of the screw D, the ring is drawn toward the front side ofthesocket, and by the set-screws it is set `in the opposite direction, andby screwing `in one of the screws E, and withdrawing the other, the ringmay be swung 'to the right or left,pivotingyupon the screw Din anobvious manner, and by'setting -up allot' the screws, the ring is heldfirmly in either position. v 4

The screws E are set in a higher place than the screw D, as seen in iig.2, for the purpose of holding the opposite side of the ring down upontherail. This mode of attaching the ring to the rail may obviously beemployed if' the ring is butpartially embraced'by the socket andoperates in thesame manner.

I do not claim broadly the employment of means for adjusting a.spinning-ring in its rail, as that has heretofore been done in severalways; but

What'I do claimfand desire to secure by Letters Patent, iss The ring,secured to the rail, and adjustable tothe spindle by th'e clamping-screwand two set-screws, substantially as described. f v

Executed, May 22, 1868.

JOHN ASHWORTH.
